Blind controller using fuzzy logic. No adaptation is performed: although the user can override the blind position generated by the controller, the latter takes back the hand after a predetermined time interval (typically one hour), and the characteristics of the controller are not adapted to the user’s wishes. Schema.
|Work carried out||
Algorithm development, simulation study, comparative measurements on two rooms of the LESO building (using a Luxmate bus for blind and artificial lighting control)
|Results||The DELTA algorithm allows an improvement of the thermal (overheating) and visual (glare reduction) comfort, together with a reduction of energy consumption (heating and lighting) of up to more than 50 % when compared to unfavourable (but unfortunately rather frequent) manual control strategies.|
